IMPROVEMENT IN NUT-AND-BOLT FASTENINGS.

Specification forming part of Letters Patent No. 131,922, dated October 1, 1872.

To all whom it may concern:

- Be it known that I, J OHN LOMA WILLIAMS, of Jackson, in the county of Madison and State of Tennessee, have inventedcertain new and useful Improvements in Fish-Plate Joints for Railway and other purposes; and do hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the accompanying drawing and to the let ters of reference marked thereon.

The fish-bar joint now most generally in use is very defective, for the following reasons: Owing to the jointsworking loose, in consequence of the jarring caused by the trains, the

. ends of the rails become battered and dangercombination of a fish-piece provided with an outer ridge extending the entire length, or

merely around the bolt-holes of the same, and

having sereworifices and a screw-bolt provided With an opening in its end, within which is I passed a split key, all as hereinafter more fully set forth. a

The figures in the accompanying drawing,

whichforms a part of this specification, more fully represent my devices.

Figure 1 represents a perspective view of two sections of railroad rails with my mode of securin g the same. Fig. 2 represents a section taken through one of the rails, showing the screw-bolt and fish-piece and the orifice in the end of the bolt Where the split or twisted key I is to pass through. I I

A A representtwo sections of railroad rails with the usualfisltpiece B on one side. 0 represents the construction of fish-piece used on the opposite side of the rails. Upon the outer side of this fish-piece is a rib or swell, to, which may be extended the entire length of the fishpiece, or maybe only on those parts where the bolt is to pass through. This rib is formed with the fish-piece proper. At suitable inter- I vals this fish-piece, as well as the fish-piece B, is formed with circular openings for the screwbolts to pass through. The orifices in the piece 0 are provided with female screw threads, while the orifices in the piece B are not. D represents the ordinary screw-bolt, with the exception that its outer end is provided with a slot, as shown in Fig. 2, through which a split key, d, as shown in Fig. 1, is passed after the bolt has been passed through the piece B, rail A, and piece 0.

In Figs. 1 and 2 of the drawing I have shown a set-screw, b, which is passed through a hole in the raise a of the piece 0, and extends down onto the screw-bolt D for holding the same tightly in its place; but I do not claim said device under this patent; neither do I wish to be understood as confining myself to the use of the same in connection with the other features of the invention.

The split key 01 may be either of spring steel or of such metal as to allow the prongs thereof to be bent outward after it is passed through the bolt.

By the invention herein described the fishpiece 0, having screw-threads, acts in lieu of a nut, and the key prevents the bolt from becoming disengaged. By means of the ridge on the piece 0 1 am enabled to pass the key freely through the slot in the bolt end, which would not be the case if the usual fish-piece is used and the key of sufficient length to prop- .erly perform its function, as the top of the rail would greatly interfere'when the bolt is so screwed as to leave the slot perpendicular, or nearly so. Besides, it gives more hold for the bolts, and consequently greater strength to the joints.

Having thus fully described my invention, what I claim is-- The combination of the screw-bolt D with a slot in its outer end, the fish-piece (l with screw-orifices and ridge a, and the key d, all substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand on this 24th day of June, 1872.

JOHN LOMA WILLIAMS.
